Novel Scheme for On-line Capacity Expansion in RAID System
一种新颖的RAID系统在线扩容方案*

To be a perfect RAID system,the on-line capacity expansion mechanism is necessary.Capacity expansion algorithms is not only disk-oriented,but also stripe-oriented.In view of generality,easiness and dynamic striping size,present a novel stripe-oriented on-line capacity expansion algorithm,which the key point lies in using two deferent configuration tables of RAID to implement the on-line data migration and load balancing in deferent RAID system.
